Abstract
Abstract— Two simple methods of phototaxis measurements have been applied to study the effects of ionophores on the negative phototactic response in Stentor coeruleus. The inhibitory effects of Ca2+‐ionophore (A23187), Ca2+‐blocking agent (Ruthenium Red), and K+ ‐ionophore (valinomycin) on photo‐taxis have been determined. Results suggest that the influx of Ca2+ plays a transducing role in the phototaxis of Stentor.
